Abstract

Organochlorine pesticides (OCPs) in waters from five sampling point in Jabodetabek area have been determined using HRGC-HRMS. A total of 21 OCPs have been analyzed, however only few of OCPs were detected. Among HCH isomers, only -HCH and lindane (-HCH) were detected with concentration in the range of ND-0,25 ng/L and 0,083 – 0,82 ng/L, respectively. Interesting result was found, where HCB was detected in relatively high in water of Ciliwung river, Pluit Jakarta with concentration of 688,28 ng/L. HCB is a compound which is not only intentionally produced as pesticide, but also unintentionally produced from industrial by-product. Therefore, contamination of the river water may come from industrial processes which are located near sampling point. If compared with river water quality criteria of PP No.82 Tahun 2001, it results were below the standard of river water quality Class I. Keywords : organochlorine pesticides (OCPs), waters, Indonesia, industrial by-products.
KONSENTRASI POLYCHLORINATED BIPHENYLS (PCBS) DAN POLYCHLORINATED DIBENZO-P-DIOXINS/POLYCHLORINATED DIBENZOFURANS (PCDDS/FS) DALAM AIR DARI DAERAH PERKOTAAN JABODETABEK Shoiful, Ahmad; Nugroho, Rudi; Fujita, Hiroyuki; Honda, Katsuhisa

Abstract

Determination of polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) in water samples from Jabodetabek urban area was conducted. In the results, a unique pattern were found interestingly in Ciliwung river, Pluit, Jakarta, where decachlorinated biphenyl (PCB IUPAC #209), and dichlorinated biphenyl (PCB IUPAC #11) were detected at relatively high concentrations as 406.77 ng/L and 6.38 ng/L, respectively. This congener pattern is different with commercial PCB mixtures, such as arochlor, kanechlor, or chlophen. Octachlorinated dibenzo-p-furan (OCDF) was also detected at a significant concentration in this water as 3.10 ng/L. Decachlorinated biphenyl (PCB IUPAC #209) and OCDF were associated with industrial by-products. Meanwhile, dichlorinated biphenyl (PCB IUPAC #11) was associated with colour pigment which widely used in consumer goods, such as paint and printed ink. Thus, PCBs and PCDD/Fs contamination might have arisen from industrial by-products where various industries located near sampling point. Keywords: polychlorinated biphenyls (PCBs), polychlorinated dibenzodioxins /polychlorinated dibenzo-p-furans (PCDDs/Fs), waters, Jabodetabek, industrial by-products.

Abstract

Climate change has impact on many sectors in the earth such as on the water resources sector. For example, the occurrence of floods and droughts in Indonesia that needs to be anticipated.  In the Technology Needs Assessment document of the Republic of Indonesia, there are three priorities technology of the water sector to anticipate the climate change. One of the technologies is recycling domestic wastewater. The recycling of waste water can be done through two consecutive stages. First, wastewater treatment processes itself to produce the quality standard limits allowed to be discharged into the environment.  Second is processing the treated wastewater till the product water can be used for particular purpose. There are many technologies can be used for water recycling process. Selection of technology depends on the type of waste water and product water quality targets. The utilization of recycled water in the community is still very little due to the barriers of technical and non-technical factors (social, economic, regulatory and others) which need to be anticipated along. Technical barrier include technology that is relatively more expensive to treat wastewater into products that can be utilized. While the non-technical barrier is many people are still reluctant to use the recycled water due to psychological factors. Therefore sosialization of waste water recycling to be expected can eliminate such barriers.   Keywords: Water recycling, domestic waste, global climate change.

Abstract

Nowadays, the domestic wastewater have become a big problem in Indonesia especially in Jakarta. The governor of DKI Jakarta has established new regulation of domestic wastewater standard which can be discharge to the environment. The regulation namely Pergub 122 tahun 2005. To comply the regullation, PT. United Can Co. Ltd. has already built a domestic wastewater treatment using anaerobic-aerobic biofilter. The wastewater treatment has 130m3/day of treatment capacities. During the start-up periods till 3 months running, the compossition of influent and efluent were analysed weekly. The results show that the concentration of parameter of COD, BOD, TSS, Amonia, pH and MBAS in the effluent have bellow the limit noted in the Pergub 122 th 2005.  Keywords:  Domestic Wastewater, Biofilter, Anaerobic, Aerobic

Abstract

Penggunaan air tanah sebagai sumber air bersih untuk digunakan sebagai air minum sering terkendala oleh kualitas air mengandung besi terlarut yang cukup tinggi. Kandungan zat besi diatas 0,3 ppm menyebabkan sumber air tersebut tidak layak digunakan sebagai sumber air baku air bersih dan untuk kandungan besi diatas 0,05 ppm menyebabkan sumber tersebut tidak layak digunakan sebagai sumber air minum.  Air baku dengan kualitas seperti itu sebaiknya dilakukan pengolahan terlebih dahulu.  Air tanah yang berasal dari daerah vulkanik aktif dengan batuannya banyak mengandung zat besi terutama dari daerah yang sering mengalami perendaman air seperti daerah bekas sawah atau bekas rawa. Proses kimiawi yang bekerja di wilayah ini tersebut pada umumnya adalah proses reduksi. Pada umumnya besi yang ada terlarut dalam air adalah sebagai Fe2+ atau Fe3+, dalam ikatan kimia sebagai Fe2O3, Fe(OH)2 Fe(OH)3 ataunFeSO4. Setelah dilakukan ekploitasi atau pengambilan air tanah dan air baku tersebut mengalami kontak langsung dengan udara, maka akan berwana kecoklatan, berbau amis seperti karat besi. Ada tiga cara penurunan zat besi dalam air yaitu dengan cara 1. Aerasi, 2. Sedimentasi dan 3. Filtrasi. Dalam percobaan ini proses penurunan zat besi dilakukan dengan cara aerasi yaitu dengan mengaplikasikan penggunaan gelembung mikro yang dihasilkan dari generator pembangkit gelembung mikro dan dengan filtrasi. Pembangkit gelembung micro ini dibangkitkan oleh pompa KTN Merk Nikuni menghasilkan gelembung udara dengan diameter 20 micron yang digunakan sebagai bahan oksidator untuk air baku mengandung besi. Setelah proses oksidasi berlangsung dalam periode waktu tertentu kemudian disaring dan diukur sisa kandungannya. Hasil percobaanadalah pada kandungan besi dalam air baku sebesar 1,16 ppm yang direaksikan dalam sebuah reactor maka efisiensi oksidasi dapat dicapai dengan baik dan berhasil menambah kelarutan oksigen dalam air sebesar 71-80 % dan menurunkan zat besi dalam air baku sampai mencapai 38-56 % pada pH 7. Kesimpulan yang dapat diambil melalui percobaan ini adalah bahwa generator gelembung mikro mampu digunakan sebagai sebuah cara untuk mengoksidasi zat besi terlarut dalam air baku dan dapat dimanfaatkan sebagai sebuah cara untuk meningkatkan kandungan oksigen terlarut air baku.Kata kunci: air tanah, zat besi terlarut, pembangkit gelembung mikro, oksidasi
